GAS-PRODUCER.

To all whom z'tmay concern Be it known that I, GEORGE B. CHAMP, a citizen of vthe United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented a new and useful Improvement in Gas-Producers, of which theI following description, taken 1n connection with the accompanying drawings, is aspeciflcation.

-The present invention relates tothat class of gas producers in which there is provided beneath the body portion ofthe producer a rotatable ash support, comprising a p relatively shallow'pan having a Haring side. VVithin said ash support and resting on the bottoml thereof is a radial arm or scraper bar,

journaled concentrically with the said ash support, which scraper bar, when held stationary with respect to the rotating ash support, causes the ashes to be crowded over the edge of the flaring side of said support and delivered therefrom.

The object of the present invention is to provide means for engaging said' scraper bar to prevent its rotation, and for releasing the same to permit of its rotation with the ash support for a predetermined period, whereby the discharge of ashes from the ash sup1 port maybe periodically interrupted and readily governed.. i

Afurther object is to make such engaging and releasing means entirely automatic in operation, thereby doing away with 'the necessity of an attendant. p

A further object is to make the operation of such engaging and releasing means adjustable, in order to permit the rotation of the scraper barat varying intervals of time with respect to the constant-rotation of the ash support, whereby a greater or less discharge of ashes-can lbe effected in a given period of time These objects, and others as will hereinafter appear, are attained by means of the construction and arrangement of parts as hereinafter described and set forth in the appended claims.

Referring to the accompanying drawings: Figure 1 is a front elevation of a gas producer, of the class described, lwith parts broken away, to more clearly show the operating mechanism for, the scraper bar. Fig. 2 is, a ,section on line 2 2, Fig. 1.,"showing, in plan, the ash supportand scraper bar se with mechanism for controlling therotation Specification of Letters Patent.

of the latte r. F ig. 3 is a sectional view on line 3-3,'Fig. 2, of a ortion of the gas producer, showing in si e velevationthe apparatus for controlling the operation of the scraper bar.

Similar reference characters refer to similar parts in the different views. Referring to thel drawings, 1 denotes the body portion of a gas producer, inclosing a heating chamber, and spaced above a rotatable ash support 2, consisting in the present instance of a relatively shallow pan, into whichashes are delivered from'the said body portion through its open bottom.l The ash support 2 is mounted upon friction rollers' 3, 3 and is rotated by means of a rotating `pinion 4 engaging an annular rack 5 upon the ash support.

J ournaled concentrlcally with the rotating ash support 2 1s a scraper bar 6, resting on the bottom of said ash support, and consisting, in the present instance, of a helically curved arm having its outer end'7 arranged .to be engaged by a latch 8, the operation of which Iwill be hereinafter described.

Journled' in bearings 9, 9 carried upon one side of a column, 10 supporting the stationary body 1 of the producer is a shaft 11, having securedA theretol at its inner end adjacent the ash support a star wheel 12, the

arms of which' are engaged by lugs 13, riveted 'to the wall of the ash support and serving to rotate the shaft 11 in predetermined relation to the rotation ofthe 'ash support, in the present instance, five or six times as fast. At the other side of said support, above the bearings 9, is a bearing 14, in alineinent with a bearing\15 carried by the stationary body portion 1 ofthe producer, and in thesaid bearings 14 and 15 is journaled a shaft 16. Keyed to said shaft adjacent its outer end is a ratchet wheel 17, and

- on either side of said wheel, mounted to turn freely on said shaft are the depending members 18` and 19, connected together at their free ends, beyond the periphery of the Wheel s 17, by a, pin 20 on which is pivotally mountconnecting rod, by the rotation of the shaft l 11 andaits vcrank arm 24, oscillates, by its connection with the cross head 23, the members 18 and 19 about the shaft 16 as a center,

. 27 projecting above the operating Hoor and l15 provided withY a series of notches 28, adapted to engage a xed pin 29, whereby the rod is held in' any 'desired position. The adjustment ef the cro'ss head causes the pawl 21 to make a 'swing of greater or less degree,

v whereby thesp'eed of rotation of thev shaft 16 is varied. .The said Wheel 17 isprevented from turning in the reverse direction by means of an oppositely engaging paWl 30, pivotally mounted on the xcd column 10.

At its inner end, adjacent the bearingl 15,

thel'shaft,l 16 has a cam 31 keyed thereto,

which cam is inthe form of a circular disk having a notch 32' in its periphery. Pivotally mountedon the body portion 1 of the producer is a lever 53, the snort arm of which -is provided with a'roller 34 engaging theperiphery of cam 31, While the end of its longer arm engages against the upper end of a `rod 3'5, slidable in guides 36 and 37 carried bythe body portion 1.

llhe'latch 8, heretofore vreferred to, takes the for'mgof a-bell'crank lever, freely pivoted 'on a bracket 38 depending fromthe stationary body portion l, and having one arm normally interposed in the path of the free end of the scraper bar 6. The other arm of the latch carries a. .forwardly projecting pin 39, disposed in' the path of the forked end 40 of thev sliding rod 35. Vhen the 4roller 84 is engaged rby the outer edgeof the rotating cam 31, the forked end of the rod 35 is depressed, thereby retaining the latchin positionto prevent rotation of the scraper bar 6. Vihen, however, the notch 32 of the cam comes under the roller 34E, the pressure of the-scraper bar@ against the latch will force the rod 35 upwardly, thereby causing the.

vroller to drop into -the notch, and the scraper bar will pass under the latch and be carried aroundthrough one revolution by the ash support. When the scraper bar .again approaches the latch 8, the roller 34: will by then have passed out of notch 32, thereby depressing rod 35,-to cause its forked end to retain thelatch in position to interrupt fthe rotation of the scraperA bar, until the notch 32 again comes under roller V34:. The proportion of the time during which the scraper bar is held stationary is determined by the relative speed of rotation of the cam 31 andthe ash suppdrt 2. For instance, 1i the cam makes one revolution during one and one-tenth revolutions of the ash support, the scraper bar ivill be held stationary during approximately one-tenth' of each revolution of the ash support. By the adjustment of lrod 26 carrying cross head 23, the spoedl of rotation of cam A31 may be varicd, thereby varying the time during which the 'scraper bar is held stationary. It is also evident that more than one notch 32 may be provided in the periphery of the cam 31, so that by varying the number ofnotches and also the speed 'of the cam, practically any desiredcombinations of time for alternately stopping and starting the movement'of the scrapeibar can be cllz'ected.
